Airfoil and Beveling Sanding Jigs?

[BigRiJoe]

Are there any jigs that would make sanding an airfoil on glider wings or beveling fin edges any easier and symetrical?

Thanks for taking the time to reply, AK. I can understand how this tools helps with the leading edge of the wing by round it, but I don't understand how it would help shape the slope on the trailing edge. Could you please explain?
